The Wiener's Circle is joining an effort to take back Chicago hot dogs after a Heinz prank left many covered in a forbidden red sauce last week.
The popular eatery is dishing out free hot dogs, covered in Gulden's yellow mustard, from 11 a.m. to 2 p.m. Monday.
The move is part of Gulden's #DefendtheDog campaign against ketchup, the Wiener's Circle said.
And the eatery known for tackling controversies head-on isn't the only one hitting Heinz after they fooled Chicagoans for National Hot Dog Day.
Heinz had unveiled its new "Chicago Dog Sauce," described as "a delicious sauce made with red ripe tomatoes and a special blend of spices and flavorings, to complement to your Chicago-Style dog," on Tuesday, in honor of the unofficial dog holiday.
The company brought the new sauce to the hands of several Chicagoans, asking them to try the red-colored topping on their hot dogs.
And many did.
But it wasn't until after they ate the hot dog that Heinz revealed its new "Chicago Dog Sauce" was actually just ketchup -- an ingredient Chicagoans adamantly avoid on their hot dogs.
Anthony Rizzo said he too isn't a fan of the new Heinz Chicago Dog Sauce -- at least not on his hot dog.
In a tweet on National Hot Dog Day, the beloved Cubs star wrote that he tried the new sauce making headlines across the city, but decided it "tastes better on my fries."
